两张网卡。一个犁，另一个不犁

  • 772

我正常敲第一张牌：

$ ping -I enp2s0 192.168.0.160
PING 192.168.0.160 (192.168.0.160) from 192.168.0.72 enp2s0: 56(84) bytes of data.
64 bytes from 192.168.0.160: icmp_seq=1 ttl=64 time=0.338 ms

我敲了第二声沉默：

$ ping -I enp3s0 192.168.0.160
PING 192.168.0.160 (192.168.0.160) from 192.168.0.65 enp3s0: 56(84) bytes of data.
^C
--- 192.168.0.160 ping statistics ---
5 packets transmitted, 0 received, 100% packet loss, time 4097ms

IPv6通过：

$ ping -I enp3s0 fe80::94a1:4767:1eb0:555d
PING fe80::94a1:4767:1eb0:555d(fe80::94a1:4767:1eb0:555d) from fe80::523e:aaff:fe16:8646%enp3s0 enp3s0: 56 data bytes
64 bytes from fe80::94a1:4767:1eb0:555d%enp3s0: icmp_seq=1 ttl=64 time=0.331 ms

传入的 ipv4 敲门有时会通过，有时不会：

$ ping -I eth1 192.168.0.65              
PING 192.168.0.65 (192.168.0.65) from 192.168.0.160 eth1: 56(84) bytes of data.
^C
--- 192.168.0.65 ping statistics ---
7 packets transmitted, 0 received, 100% packet loss, time 6137ms

或者

$ ping -I eth1 192.168.0.65
PING 192.168.0.65 (192.168.0.65) from 192.168.0.160 eth1: 56(84) bytes of data.
64 bytes from 192.168.0.65: icmp_seq=1 ttl=64 time=0.180 ms

传入 ipv6 正常：

$ ping6 -I eth1 fe80::523e:aaff:fe16:8646
PING fe80::523e:aaff:fe16:8646(fe80::523e:aaff:fe16:8646) from fe80::94a1:4767:1eb0:555d%eth1 eth1: 56 data bytes
64 bytes from fe80::523e:aaff:fe16:8646%eth1: icmp_seq=1 ttl=64 time=0.312 ms

我错误地配置了一些东西。请说明原因。以及如何解决它。

在gbg的回答之后，临时解决方案是：

# оставил только ipv6
        enp3s0:
            addresses: [ "fe80::523e:aaff:fe16:8646/64", "2a03:e2c0:bde:5555:523e:aaff:fe16:8646/64"]

    在两个适配器上设置了相同的网络192.168.0.0/24- 这将不起作用。为此，您需要在交换机和 Linux 机器上设置端口聚合。
